The use of shackle series products and matters needing attention

The use of shackle series products and matters needing attention

1. Before use, check whether the type of shackles used is matched and whether the joints are firm and reliable.

2. Do not replace pins with bolts or metal rods.

3. There shall be no major collision or collision during lifting.

4, the pin shaft in the lifting hole should be flexible rotation, no blockage phenomenon.

5. The shackle body should not bear the transverse bending moment, that is, the bearing capacity should be in the body plane.

6. The maximum working load of shackles can also be adjusted when the shackle bearing capacity is at different angles from the body plane.

7. The maximum Angle between the legs of the shackle shall not be greater than 120°.

8. Shackles should support the load correctly, that is, the force should be along the axis of the shackle center line to avoid bending, unstable load and overload.

9. Avoid partial load of shackles.

10. When shackling, it is used to bind with the wire rope. Part of the horizontal pin carabiner should be connected with the wire rope to avoid the friction between the wire rope and the release of the shackling rope, resulting in the separation of the horizontal pin body.

11. Reasonable periodic inspections should be determined according to the frequency of use and the severity of the working conditions. The period of periodic inspection shall not be less than half a year, and the longest shall not exceed one year.

12. If used in high temperature environment, load reduction should be considered, as shown in the following table:

The use method and matters needing attention of hook series products

1. When using the hook, the end of the rigging should be hung on the force center of the hook, not directly on the tip of the hook.

2. When the hook cracks and deforms, it is strictly prohibited to repair the hook by welding and heating bending.

3. When placing the two cables into the hook, the Angle between the vertical plane of the cables and the sling must not be greater than 45°, and the Angle between the two cables must not be greater than 90°.

4. Hooks worn beyond the limit shall not be used.

5. When using the hook, it is not allowed to use the hook for side load, rear load and top load.

6. Under any of the following circumstances, it shall be replaced or scrapped

1) The corrosion or wear of the hook body exceeds 10% of the nominal size.

2) After inspection, it can be seen that the hook has cracks, cracks or cracks.

3) The hook of the warranty card is loose and the function is lost.

4) The hook warranty card cannot work normally due to the increase of the opening size of the hook, or the radian between the tip of the hook and the plane of the hook body is greater than 10°, or the damage, bending and wear of the hook tip caused by any reason.

The use method and matters needing attention of the ring series products

1. The maximum allowable working Angle of the sling ring is 120°.

2. When cracks and deformation occur in the ring, it is forbidden to repair the ring by welding and heating bending.

The use method and matters needing attention of chain shackle series products

1. Select proper chain shackles according to the chain diameter and bearing capacity. Overloading is strictly prohibited.

2. When installing chain shackles, first put the buckle body into the sling ring or chain ring, rotate the buckle body to check whether it is flexible, then align the two buckle bodies, install the clamping spring, and Pierce the horizontal pin.

3. When the spring of the chain shackle becomes loose and fails, it should be replaced or scrapped.

4. Chain shackles shall not be twisted or misaligned. If any abnormalities are found, the use should be discontinued.
